This is the 2nd time in maybe a year that i've seen Premiere misrepresent my graphics. I rend ered out this font from After Effects and it didnt have these blue jaggies on it. When I rendered it out of AE, it looked GREAT! and It looked great in premiere. and then you come back a day later and it looks awful with these nasty jaggies all over the text. It happened months ago and then last week. So I re-rendered the graphic from scratch in AE. brought it into Premiere and it looked great. Then a day or so later I open my project and the issue is back. I purged the cache. didnt help. I'm playing in full resolution. What a nightmare.
